SAP is one of my focus areas at work. My answer would be to install the trial version (which I think is no longer called miniSAP, but used to be), try to get the general hang of how it's supposed to work, and then dig deeper in the areas that interest you, maybe Java or ABAP development if you want to do development. Last time I've used it, the trial version had a 90 days license, but you could renew it easily and legally.
You won't get a SAP job that way, but it might give you enough of an edge to take on SAP-related projects (think "sure, I've done webservice calls into Salesforce and I know how that works with SAP XI, happy to work on your integration project").
